Implement frameskip feature

[LuisPerss]

Is there an existing issue for this?

• I have searched the existing issues

What feature are you suggesting?

In Mandarin, this option was rescued, which basically serves to skip frames like in Drastic on DS in order to gain greater stability or FPS. It would be a good addition to the emulator and could even be improved so that it would look more like Drastic.

Why would this feature be useful?

It would be nice to have the option to save resources and have FPS increases depending on the option you choose, there is X2, X4X8 and X16, and they would have the option to do it automatically or manually.

Mandarine's implementation of frame skipping was previously rejected due to concerns of code quality, so implementing this feature wouldn't permit bringing the code over from there

This is the message exchange in the Discord where it was briefly discussed: https://discord.com/channels/1222589950365794477/1224774209201242123/1262767756428710039

Tbf that option in Mandarine is not all that great, Never was usable imo unlike PPSSPP abd others

Hopefully someone makes a proper frameskipping implementation later on
